WVILSON GEORGE ROSS, OF BENICIA, CALIFORNIA.

ACETYLENE- -GAS GENERATOR.

EEECIFICATION forming part of Letters lPatent N0. 670,81 5, dated March 26, 1901.

Application filed June 6, 1900. Serial No. 19,241. (No model.)

To ctZZ whom, it may concern:

Be it known that I, WILSON GEORGE ROSS, a citizen of the United States, and a resident of Benicia, in the county of Solano and State of California, have invented a new and Improved Gas-Machine, of which the following is a full, clear, and exact description.

This invention relates to improvements in machines for generating gas from calcium carbid; and the object is to provide a machine of simple construction having, in connection with a receiver or gasometer, a plurality of generators and having a means for automatically placing a generator in operation after the cal-bid of a previously-operated generator shall have been exhausted, and, further, to provide a novel means for controlling the discharge of gas from the generators.

I will describe a gas-machine embodying my invention and then point'out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partial elevation and partial sectional elevation of a gas-machine embodying my invention. Figs.2 and 3 are detail views showinga device for lockinga generator-cover and also forholding an air-vent valve in closed position, and Fig. 4 is a sectional detail showing a means for supporting the carbid-holder.

Referring to the drawings, 1 designates the shell or outer casing of the receiver or gasometer, and 2 the bell movable therein in the usual manner. Having connection with the gasometer is a plurality of generators, here shown as two in number, A and B. It is to be understood, however, that a greater number may be employed. As the generators are similar in construction, the description of one will answer for both.

The generator consists of a shell 3, having a jacket 4 for containing water and into which the downwardly-extending flange portion 5 of the cover 6 passes. The cover 6 is provided with a blow-off or air valve 7, and the stem 8 of this valve is attached to a hook 9, adapted for engagement with an eye 10 on the jacket 4. Upon placing the cover in position the valve 7 is to be opened, so as to permit the escape of air. At this time the hook 9 will be in the position indicated in Fig. 2; but after replacing the cover the hook 9 is to he engaged with the eye 10, as plainly indicated in Fig. 3.

Arranged within the generator-shell is a carbidholder 11, in which carbid trays or grates 12 are removably placed, these trays or grates having perforated bottoms. The holder 11 is supported by legs 13, which engage with arms 18, attached to a cover 17, and is held above a receptacle 14, designed to receive the ashes of the cal-bid. This receptacle 14 is supported in a vessel 15, and it is provided at the bottom with a removable closure 16. The cover 17 is placed over the holder 11, and this cover, with the holder, is supported by means of a bar 18, attached thereto and engaging with pins or lugs on the inner side of the shell 3.

From the holder or from the cover 17 thereof a pipe 19 extends into a water-tube 20, the top of said water-tube being made in the form of a funnel, shaped as an inverted cone, through which the pipe 19 loosely passes, so that gas may pass up through said funnelshaped top at the outer side of the pipe. water-tube 20 is connected by means of a pipe 21 with a plunger-pipe 22, in which a plunger 23 is mounted to move. The plunger 23 of the cylinder A is connected to a lever 24, fulcrumed on a bracket 25, attached to the gasometer-shell 1, and a rod 26, attached to the hell 2, has a head 27, adapted to engage with the upper side of the lever 24 to move the plunger 23 upward, as will be hereinafter described.

The plunger-valve 23 for the generator B is connected to alever 28, also fulcrumed on the shell 1, which has an operating-rod 29, the said rod being connected to the gasometerbell and having a head for engaging with the upper side of the said lever '28. The heads 27 and 30 are so arranged on the rods 26 and 29 that when the gasometer-bell moves downward the head 27 will first operate the lever 24 to raise the plunger 23. After all of the carbid shall have been consumed in the generator A the generator B is to be putinto operation by means of the head 30, engaging with the lever 28, operating the plunger 23 for said generator B.

The

rise in the water-tube 20.

From the generators gas-supply pipes 31 extend into an absorber and cleaner consisting of a cylinder 32, adapted to contain water in its lower portion and into which said pipes 31 extend, and above the water and supported on a sieve-like bottom 33 is an absorbent material 34, designed to absorb the water from the gas passing therethrough. From the upper portion of'this cylinder 32 a pipe 35 leads into the gasometer and terminates above the water-level therein, and leading from the gasometer is a gas-supply pipe 36, having a curved portion or trap 37 at its lower end, designed to receive any moisture that may be carried from the gasometer by the gas.

In operation when the gas is nearly exhausted from the gasometer the lowering of the bell 2 will cause the head 27 to engage with the lever 24, which will operate to raise the plunger 23, permitting water to flow from the water-tube 20 into the valve-tube 22. The water thus being lowered in the water-tube 20 will offer very little resistance to the gas. Therefore the gas will pass up through said water into the generator, above the water-level thereof, and then pass through the pipe 31, through the absorber and c1eaner,and into the gasometer, this gas being made by the water which is in the generator passing up into the carbid-holder, this being possible by the release of pressure in the holder 17, said release of pressure being caused by the water lowering in the tube 20. As the gasometer bell rises the plunger 23 will settle down into the tube or plunger-pipe 22, which causes the Water to The rising of the water in the tube 20 will stop the gas from coming out through it, and consequently force the water down from the carbid trays or grates 12, practically stopping the making of gas until the gasometer-bell again lowers and liftsthe plunger 23 When the carbid in the first generator shall have been consumed, the generator B will be brought into operation, as before describedthat is, upon the lowering of the bell the lever 28 will be rocked to move the plunger 23 upward, permitting the gas to escape from said generator into the gasometer.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1..In a gas-machine, a gasometer or reoeiver, a generator having connection therewith, a water-tube in the generator, a pipe leadingfrom the carbid-holder into said tube, a tube on the outer side of thegenerator, and a plunger operating in said tube to regulate the depth of Water in the Water-tn be, substantially as specified.

2. A gas-machine, comprising a gasometer or receiver, a generator having connection therewith,a carbid-holder in the generator, a water-tube arranged in the generator, a pipe leading from the holder into said Water-tube, a plunger-tube arranged at the outer side of the generator and having a pipe connection with the Water-tube, a plunger operating in said tube, and means actuated by the lowering of the gasoineter-bell for moving said plunger, substantially as specified.

3. In a gas-machine, the combination with a generator and a gas-discharge pipe for the generator, of a tube on the outer side of the generator and having communication therewith, a gas-discharge pipe communicating with said tube and a plunger operating in said tube to vary the water-resistance to the gas-discharge from the generator, substantially as specified.

4:. A gas-machine, comprising a gasometer, a plurality of generators arranged adjacent thereto and having pipe connection therewith, tubes for containing water on the outer sides of the generators, pluugers operating in the tubes for controlling the flow of gas from the generators to the gasoineterdevers with which said plunger connects, rods extended along the gasometer-bell, and heads on said rods for operating the leversvone after the other, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
